I'm using ASP.Net but my question is a little more general than that. I'm interested in reading about strategies to prevent users from fooling with their HTML form values and links in an attempt to update records that don't belong to them.
For instance, if my application dealt with used cars and had links to add/remove inventory, which included as part of the URL the userid, what can I do to intercept attempts to munge the link and put someone else's ID in there? In this limited instance I can always run a check at the server to ensure that userid XYZ actually has rights to car ABC, but I was curious what other strategies are out there to keep the clever at bay.
I have 4 links on my asp.net page which open documents on an internal server which is behind firewall. I realized this was incorrectly designed as these links do work while i am the internal network they would not work for an end user accessing the web site outside the network as the links point to a resource on a secure server which is not accessible outside the network.
I'm just wondering what people use to stop user from click a submission button more than once thus creating many records. Does any one have any examples that take client-side validation into account. I have done much research on this but am yet to find a feasible solution.
I realize what I am trying to do is a little unconventional; but I want to make my search SEO. Basically I want the query string resulting from my search to be human readable; if I was doing straight html this would be cake:
I realize that I can change the form method in asp.net, however, all the asp.net state holders show up in the query string. I even tried disabling viewstate and removing all javascript submitting controls (to get rid of __EVENTTARGET) to no avail.
The thing is, I really want to keep using the same master page as I do in the rest of the site; does any one know of anything I can do short of building the page from scratch?
I'm working with an asp.net application that produces large PDF documents from HTML. The content is perhaps complex (detailed grid type listings, css styled, running to 40+ pages) compared to typical usage. None of the libraries we've tried are performing adequately. Typically a 40 page document is taking upwards of a minute to render on a powerful multi-core machine.
We are able to decouple the generation from the web application and also pre-generate documents in some cases. Still, the frequency with which content changes requires a faster solution.
So, does anyone have experience of a PDF generation component that can output a content heavy 40 page document in seconds rather than minutes? Or are our expectations unrealistic?
NB: I'd rather not "out" the poorly performing components here as we are seeking support from vendors to make improvements. I've reviewed previously questions posted on StackOverflow and none appear to deal with this type or size of document.
I need to put together an aspx page on which the user specifies a word document. These docs are all in the same format. I need to retrieve text from form fields in the documents and then insert these into a SQL server. I'm completely new to this kind of thing. Can anyone outline the principles behind what I need to do, or point me to a site which will explain it in simple language.

I need to display a (pdf,doc,docx,txt) documents inside an asp.net web form with the ability to select a part of the document content and do some processing on it in the right click (like saving the selected content to DB)?
Im working on a little hobby project. I already have written the code to get a url, download the header and return the mime type / content type.However, the step before this is the one im stuck on - i need to retrieve the contents of all the urls on the page based inside a tag, and in quotes i.e.
My company purchased ActivePDF WebGrabber a couple of years ago to convert a classic ASP created HTML page into a PDF form. The only drawback with the tool that we continually run into is that the outputted HTML links are not hot. Are there any tools that do include hot-links within the HTML to PDF output?
According to the ActivePDF FAQ for Does WebGrabber convert hyperlinks into usable links in the output PDF?, the answer is no. There is a phrase confusing me at the end of the answer:
"To implement links in the final PDF, the application would search for links prior to the Postscript generation, and append them once the PDF has been generated using Toolkit."
Does that mean this is how to achieve it, or is this their theoretical but not tested solution? If this is the solution, has anyone done this that might be able to post some sample (pseudo-)code?
Edit: I should mention that we're open to a different tool, and we need it to be accessible via classic ASP and ASP.NET. I would prefer a solution in which the links are automatically hot-linked during PDF generation.
I have a HTML file which I want to load, say in a Label control. This HTML file have a series of unordered list, which acts as a vertical menu links for the various sections of the file.Now, I have no idea whether these links, inside the HTML file, will work if I load it on Label control. Is there any other way of doing this ? I want those links to work when the file gets loaded.
Should bar on the HTML designer show the tag name? It sometimes does!
Here's an image of what I referring to.
I thought for sure it must be a bug but considering that I heard that MS was rewriting the editor (designer too?) I am starting to question whether I know how to use it!
Note the "TD" tooltip on the bottom right. Shouldn't this "TD" appear on the bar on the far right where the mouse would be?
I have some HTML markup in my ASP.NET master page representing a basic navigation menu. THree words that link to three pages. My CSS and HTML are included below for your reference.
When I load the page, the links appear with the correct color (red). If I hover over a link, the link changes to the correct color (blue). So far, we're good. Clicking a link changes the link color to the correct color (yellow). The two remaining links are still red / blue as expected. Clicking a second link changes that link to yellow also. Now I have two yellow links. Neither yellow link displays the hover color (blue) like I'd prefer. Clicking the third link causes it to be yellow, too and none of the links display the hover style.
Although a link has been clicked, I'd like the color to be stored and have the hover color displayed. How do I accomplish this? This is an ASP.NET web application project but I'm only using straight HTML at this point.
I have programatically added javascript to HyperLink controls on all pages in my site from the Masterpage as it is served up.
I have a new problem. I have a Masterpage wrapper around html pages without asp.net controls in them. Using the Masterpage, I need to parse through all html hrefs in each page and add javascript to each link if it includes "http" or ".pdf". Can the Masterpage parse the text of each page and programatically change it?
When someone requests a web form, I want to use Javascript to see what browser they use, and then point to the correct css files with Javascript. What is the simplest way to do that.
For example, in my header of the html form, I have a link that says:
where the RecentArticles Action (in ArticleController) is :
[ChildActionOnly] public ActionResult RecentArticles() { var viewData = articleRepository.GetRecentArticles(3); return PartialView(viewData); }
and the code in my RecentArticles.ascx partial view: <li class="title"><span><%= Html.ActionLink(article.Title, "ViewArticle", new { controller = "Article", id = article.ArticleID, path = article.Path })%></span></li>
The problem is that all the links of the articles (which is built in the partial view) lead to the same url- "~/Article/ViewArticle" . I want each title link to lead to the specific article with the parameters like I'm setting in the partial view.
I would like to create a database where users can search for multiple fields. For example: if the record is personal details info like name, address, phone number and email id i would like to generate link for this automatically with the fields using stored procedure.. Is that possible.? If so can anybody provide me with the line of code or guideline on how to do that?
I'm hoping this is an easy one...I'm using Microsoft.Office.Interop.Word to convert uploaded word documents into previewable html files. I haven't implemented it fully, but I've played around with it enough that I think I have a plan that will work... My question revolves around
[Code]....
I'm not in love with the idea of opening word and closing it everytime there's an upload (which I hope is a lot of the time) I'd like to make this a shared object that loads at application start. I have 2 questions that go along with this. 1. I imagine that winword could lock up and that would be a problem, right? 2. to save a document I use wordapp.ActiveDocument, this could have an issue as a shared object, right? I think I'm talking myself right out of this...
I have a simple ASP.NET page that uses the VLC media player to play a video in IE. I also have four buttons to control the playback:
Play, Pause, Stop, and Mute
The four buttons call JavaScript functions that access the ActiveX control. When I click on any of the buttons, I get the following error in the JavaScript function:
"Microsoft JScript runtime error: 'vlc' is undefined".
However, if move the object tag for the vlc player outside the form tag, then the JavaScript works correctly, and I can control the video playback.
My question is why must the object tag be outside the form tag for this code to work correctly?
This is the content in the master page as you can see there are 4 menu items i tried to form as sidebar and i tried to inherit in home.aspx(one of the content pages) as follows:
But unfortunately the sidebar is not at all getting displayed. I know i'm doing fundamentally wrong some where. My intention is to have web pages to have sidebar like this. It is a screenshot of my intended page.
